This video covers installation and inflation of Kavan tires on the big cub. Had to make a special tire inflation adapter. Also made a deflator tool out of a large paper clip. The stock tires weigh 91g, these Kavans only weigh 93g! They are very light in comparison to Dubro's.

24 July update. Flew for the first time with the new tires. I gave each one two strokes of the pump I rigged up. That was too much, will go with one stoke next time to keep down the bounce upon landing. They are very responsive during the taxi around the field.
